Abstract

There is provided a liquid formulation ejection device which improves reliability of inhalation even in a case where a preejection is performed and resolves a concern about hygiene. The liquid formulation ejection device (1) ejects a liquid formulation in a form of liquid droplets into an inhalation flow path (20) and allows a user to inhale the formulation. The liquid formulation ejection device (1) includes an ejector (11) for performing normal liquid droplet ejection for inhalation and liquid droplet preejection not for inhalation, and a discharger (13, 14, 28) for removing liquid droplets ejected by the liquid droplet preejection out of an inside of the inhalation flow path (20).

Description

[0001] This application is a National Stage filing under 35 U.S.C. §371 of International Application No. PCT / JP2006 / 318207, filed Sep. 7, 2006.TECHNICAL FIELD

[0002] The present invention relates to a liquid formulation ejection device such as a drug ejection device which is so configured as to be portably carried by a user and ejects a drug as fine droplets allowing the user to inhale the drug.BACKGROUND ART

[0003] In recent years, the average life expectancy has been increasing to thereby increase the elderly population because of the advances in medicine and science. However, the change in dietary habits or living environments and the environmental pollution have increased, and new illness and infectious diseases due to viruses or fungi have appeared, so that anxiety to the health of the people has been increasing.

[0027]FIG. 1 is a perspective view showing an external appearance of an example according to the present invention. In the figure, reference numeral 1 denotes a device main body, reference numeral 2 denotes an access cover, reference numeral 3 denotes a front cover, and a housing is composed of these components. Reference numeral 5 denotes a lock lever which engages with a protrusion provided on an end of the access cover 2 such that the access cover 2 does not open in use. In order to achieve the locking, the lock lever 5 is formed such that a claw-shaped portion provided at the front edge of the lock lever 5 urged by a spring engages with the protrusion of the access cover 2. When sliding the lock lever 5 downwardly, the access cover 2 opens with a hinge axis 7 (shown in FIG. 2) being used as a rotation center by the force of an access-cover-returning spring 6 urging the access cover 2. Moreover, reference numeral 31 denotes a display LED which displays that an ejection unit or mo...
